blob
====
This crate provides a dedicated `Blob` structure for use in storing,
encoding and decoding to/from base-64, with support for type-level encoding
configurations suitable for url-safe base-64.
When serializing, it will encode the binary data as base-64, and when deserializing it
can either read and decode a base-64 encoded string or a raw sequence of bytes.
Example using `FromStr::from_str`:
```rust
extern crate blob;
use std::str::FromStr;
use blob::Blob;
fn main() {
let my_blob: Blob = Blob::from_str("AQIDBAU=").unwrap();
assert_eq!(my_blob, [1, 2, 3, 4, 5]);
}
```
